Sage + Vite repo help

I was keen on trying vitejs and found this Sage + Vite repo which seems really good:
GitHub - ravorona/sage: Wordpress theme, based on Sage starter theme

I wondered if anyone here has tried this? I have the latest dev-devlop branch running on top of Bedrock (without using Trellis) and can compile with yarn build, but I’m having trouble getting HMR loading in my browser when running yarn dev. I keep hitting a page which just reads “Cannot GET /” when I try to access any of

My env reads:


# Certificates
# HMR_HTTPS_CERT=path_to_cert
# HMR_HTTPS_KEY=path_to_key

# If true hot reload is active
# HMR_ENTRYPOINT=http://example.local:3000

I have tried different versions of this, commented out HTTPS parts as I’m not using a certificate locally. The last two lines are taken from the repo but the first 3 lines are new on dev-develop, so Ive tried different combinations of using them or not.

Has anyone else got HMR working, and could you point me in the right direction? I suspect its something obvious that I’m overlooking!

Many thanks
